Shot from directly overhead, this sharp black-and-white real-photo postcard reveals the Library of Congress in Washington, D.C. in breathtaking aerial perspective — the ornate Italian Renaissance Main Building (Thomas Jefferson Building, completed 1897) anchors the foreground with its great octagonal dome, while the clean Beaux-Arts lines of the John Adams Annex Building (completed 1939) extend behind it, both structures surrounded by the leafy Capitol Hill neighborhood. Real-photo postcards of iconic federal buildings are perennial favorites among Washington D.C. topographic collectors, and this Kodak paper example — blank and unused on the reverse — carries the undivided simplicity of a souvenir acquired in person. The crisp photographic detail captures automobile traffic on the adjacent streets, offering an unexpected urban-planning time capsule.
